From what I understand, the dash is vinyl. I am still looking for a product that will protect the vinyl dash, the exterior black plastics, etc., but will not change their appearance (i.e. leave a glossy shine).
On another thread a poster suggested Meguiar's NXT Tech Protectant. I looked all over town for it and when I couldn't find it, I finally called Meguiar's. They no longer make that product. The rep suggested Meguiar's Ultimate Black.
Another poster suggested 303 Aerospace. I think that can only be purchased online.
The dealership suggested a product that they carry, but they were out of it. Now they have it in, but they are too far away to make a trip just for that. We have a Ford dealership that's closer so when we're in that area, we may try to get the product (sorry can't remember what it's called) from them if we don't find something else first.
Our MKC is garaged, but we have a dash cover that we use when we're out and about, especially for the summer as it gets very hot where we live.
